Tennant releases its T300 Walk-Behind scrubber. Among the innovations available for the first time on a Tennant walk-behind scrubber are LCD Pro-Panel™ controls and ec-H2O NanoClean® Technology. ec-H2O NanoClean Technology offers the same great benefits of the first generation and now cleans better by cleaning more soils in more applications.**
* Based on a study by EcoForm™.
** ec-H2O NanoClean cleans more soils in more applications than the original ec-H2O. ec-H2O NanoClean technology is not suitable for all soils, including heavy concentrations of fats and oils. Depending on the type of soil, conventional chemical cleaners may be required.
